brown patches and some yellow spotting

[Stems]

flowering one bag seed and two skunkberry plants from peakseeds. have more on the way in veg from peakseeds. but anyways i don't think the leaves are laying in a healthy way, esp. on the bag seed plant, they are somewhat currled under/droopy and a fair amount of yellowing is apparent on the lower leaves. on the bag seed plant there are a couple brown patches that just appeared overnight, on an otherwise green leaf, right in the middle. i just fertilized last night too.. it doesn't appear to be nute burn but possibly too much of something?



plants vegged for 7 weeks and have been in flowering under 400w HPS for 15 days now. last PH runoff test (about 2 weeks ago) was right around 6.5 so i don't think that is an issue but i should probably check again.



for ferts they have been getting miracle grow 24-8-16 and now getting 18-18-21 for flowering, about every once a week in half strength from suggested on box.


any ideas as to what could be causing the curling under of leaf tips?? and the yellowing? your help is appreciated, thanks in advance!

the bag seed is curling and drooping a lot more than the skunkberries, overall they are a lot more healthy looking. certainly good, just growing the bag seed for extra experience.

The bagseed plant. note the brown!

seems to have gotten worse in the bag seed plant. it isn't some plant virus is it? that what i am most worried about, don't want it to affect the other babies.

EEK!! id say over watering... and not enough soil. you need to transplant those bitches into the same pot, put a good layer of soil on the bottom and put the plant in and fill it up to almost the top. when you water water slowly until it comes out the bottom. then dont water agian until the leaves start to droop or until you dip your finger in the soil and your finger comes out clean free of moisture. oh ya and i wouldnt use miracle grow.... miracle grow is poop. good luck

I think overwatering as well

How can over-watering cause brown and yellow spots? Maybe its root bound but I don't see how its from a watering problem.


And on the subject of MG, I personally use MG 7-7-7 for my veg stage. It works well for me.

[H3mp-16]

Oh yeah, you want more P during the flowering stage so try a 15-30-15 or something similar.

thanks for the help so far. i did repot them, a little bit root bound so that should help them out with 3-4 inches of fresh soil below.

unfortunately, the plants are not looking better right now. some brown areas have appeared on one of the the skunkberry that are exactly like what had appeared on the bagseed, which looks pretty bad right now.


i was wondering if this could be a ventilation/heat issue in our closet setup?

there is an 8" inline duct fan that can move ~300cfm but our closet is something like 70cf. could this be drying out the plants? the duct isnt actually attached to the HPS light fixture, its just right next to it, sucking near the plants too.


or possibly the fan is not running optimal cfm and the 400w HPS is causing heat damage?


take a look.


This is the bagseed.



Here is a close up of the new brown on the skunkberry, right on the top. which looks like it had gotten some heat damage.

this was probably a combination of light heat/light burn, slight root bounding, and slight over fertilization.

[DankNess]

i dont think light burn... since they are so stretched out.. plus if it was the lights the tops would be mad burnt

root bound and over nutes most likely. id ditch the MG cus it seriously sucks and cuases hermies... ask me how i know

its all about Fox Farm. get it use it love it.


how are you watering them? is there any soil in there or no?

The large dead splotches indicate a simple Phosphorus Deficiency. Lower your PH to 6.0 and water with a natural nute higher in P. I sugest a Bat Guano fert. The tips burns and curling also indicate overwatering and a N overdose, but overall the P is the issue. PEACE!

[law_101]

you said peakseeds is where you got your seeds? Or is that peakseedsbc.com ? How are they on everything

[hindu42O]

the brown spots at the top of plant R light burn.....the bronze

The drooping and other browning looks to be overwatering or nutes.

what do I know though. iv only a few post and there is no way iv been doing this 15 years, because i just joined the only forum dealing w/pot on the internet,.

peace.....

It sounds like you are right on.

I got a digital pH tester and it appears the soil is around 6.7 to 7. My tap water has a pH of 7, what is the best way to lower the pH? Can I add a small amount garden lime to the water and water it in?

I got bone meal for a fertilizer, can that be watered in or does it need to be mixed with the soil?

they are awesome. ordered a variety pack for 40$ which is supposed to include 20 seeds but received about 24 seeds. just don't expect it to get to you any faster than 4 weeks in the US. the genetics appear to be pretty damn good, i smoked a bunch of my friends skunkberry who got me started with a couple seeds and it was an excellent high.

[aisispoet]

ok lime is a base not an acid so it will make your ph go up or more likely will just stabilize it at 7 or 8ish. The best thing to use to lower the PH(make it more acidic) is to use a natural ph lowering agent such as the one available on altgarden supply here: http://www.altgarden.com/store/cart....t_detail&p=422. As for bone meal, you can add 1 tsp per plant and work into the top three inches of the soil and water with plain ph adjusted water 6-6.5 ph.

[hindu42O]

.5 off in ph will not cause those problems.

the big bronze spots r light burn...period.

the drooping is due to too much water. the tips r too much N.
